I use pre-emergent in several non-lawn areas with varying results. I use it in spring rather than fall.
The trick is to have it affect the seeds you want to suppress but that varies each year as seeds blow in at different times, rain will get the pre-emergent to different levels, and temps will make a slight difference in germination schedule.
you use pre-emergent like the name says. In colder climates, this means spring, usually early. If you are in the south, and there are fall germinating weeds, then yes, a fall application would be appropriate. You might want to check locally regarding the existence of fall germinating weeds and the timing of pre-emergent application.
I lived in the south, Dallas area. There, we had no fall germinating weeds.
Yes, Alabama zone 7B. I usually apply fall pre-emerge in October (depending on soil temps - 50F is about right). You may be able to find soil temperature data if you search for an area 'mesonet'; Auburn University has a mesonet website for Alabama.
Do you apply a Lawn Fall Pre-Emergent Herbicide for Fall/Winter weeds?
I always think an opening question in a new thread is the member in need of help. But apparently it sounds like you don't need any based on this thread you started.
Do you use something like Preen in those non-lawn areas?

Weeds actually grow year round, contrary to popular belief, just difference types.
For example, you won't have crabgrass thrive in late fall with cool temps, nor will you have chickweed in the peak of summer with temps in the 90s.

Weeds don't grow here in the winter...too much snow, usually. And the freezing temps probably don't help either...
